No.  The BROCKLEY domain is on a internal private network.

192.168.18.161 is the private address assigned to SMB4-1.brockley.harte-lyne.ca.

Yes:
ping  aac648b2-aac8-411d-afe0-7cbd5455841c._msdcs.brockley.harte-lyne.ca
PING SMB4-1.brockley.harte-lyne.ca (192.168.18.161): 56 data bytes
ping: sendto: Host is down

No.  SMB4-1 was the original DC name when we were converting from CentOS to
FreeBSD.  We had numerous difficulties with transferring ACLs with rsync as I
recall. At some point during the transition efforts SMB4-1 became corrupted or
unusable in some fashion so the conversion target was switched to a new DC
SMB4-2.

It was always intended to re-establish an alternate SAMBA DC but we never found
the time once the conversion was finished.  At this point we just need to erase
it.

I believe we were told to never attempt to add a DC with the name SMB4-1
following this.

Then I think that is your problem, whilst SMB4-1 no longer
physically exists,it looks like there are still traces of it in your AD
DNS. You will need to find these and then delete them, just like you
did with the duplicate PDC_Emulator SRV record.
